How to send sms using C# and twilio API

Question

I'm trying to create a User interface where the user can enter her credential and phone number and send messages to some recipient using Twilio API

So as explained I created my account and initialized the Authentication key and token

    private void button1_Click(object sender, EventArgs e)
    {
         string ssid = twilioSSIDBox.Text;
         string token = twilioTokenBox.Text;
         string number = twilioNumberBox.Text;


        var client = new TwilioRestClient(Environment.GetEnvironmentVariable(ssid), Environment.GetEnvironmentVariable(token));
        client.SendMessage(number, "+158965220", "Teting API message!");

    }

After multiple test (hard coding the ssid and token and number ) and documentation consulting , the message is still not being sent on the visual studio platform and I'm not receiving any error message or anything

So my question is what I am missing? Do I need a certain library that allow visual studio to be able to send sms messages?

I'm using Visual studio 2015 and windows 10 platform

Thank you

Their docs seem pretty straight forward. https://www.twilio.com/docs/quickstart/csharp/sms/sending-via-rest — Nico, Mar 06 '17 at 05:46
So, from where do you want to take the Twilio 'ssid' and 'token', from text boxes or from environment variables? — Alex Baban, Mar 06 '17 at 08:19

I end up resolving my problems

so this was not working on VS2015 Platform :

    var client = new TwilioRestClient(Environment.GetEnvironmentVariable(ssid), Environment.GetEnvironmentVariable(token));
    client.SendMessage(number, "+158965220", "Teting API message!");

Even thought I already installed the Twilio api version 4.7.2 using nuget console

I did again the following :

Install-Package Twilio

than Visual studio suggest me to add reference to the API inside the code

 using Twilio;
using Twilio.Rest.Api.V2010.Account;
using Twilio.Types;

Thanks to the following Example

this has worked :

 TwilioClient.Init(accountSid, authToken);

        var message = MessageResource.Create(
            to: new PhoneNumber(toNumber),
            from: new PhoneNumber(FromNumber),
            body: "Hello from C#");

So my conclusion is probably an outdated library because when I used NUGET to install:

Install-Package Twilio -Version 4.7.2

I have no idea why it wasn't working

P.S: I'm not sure if it was relevant but I also installed this using NUGET console it mighed helped or it might not but I felt like I had to mention it :

Install-Package RestSharp

See if you can get any help from the below code:

/// <summary>
    /// Sends alert as SMS 
    /// </summary>
    /// <param name="details"></param>
    /// <returns></returns>
    public static Message SendSms(DeliveryDetails details)
    {
        var messageResult = new Message();
        try
        {
            if (details?.ToNumber != null)
            {
                var toNumberList = details.ToNumber.ToList();
                if (toNumberList.Count > 0)
                {
                    foreach (var toNumber in toNumberList)
                    {
                        messageResult = Twilio.SendMessage(FromNumber, toNumber, $"{details.Subject}\n\n{details.Message}");

                        if (messageResult == null)
                        {
                            logger.Error(string.Format(
                                "Error connecting to Twilio, message sending failed to {0}",
                                toNumber));
                        }
                        else if (messageResult.RestException != null)
                        {
                            logger.Error(string.Format("Twilio Error Message Description - {0}",
                                messageResult.RestException.Message));
                        }
                        else
                        {
                            logger.Info(String.Format("SMS {0} deliverd to {1}", messageResult.Body, messageResult.To));
                        }
                    }
                }
                else
                {
                    logger.Error("ToNumber List Empty");
                }
            }
            else
            {
                logger.Error("ToNumber List Null");
            }
        }
        catch (Exception e)
        {
            logger.Error(String.Format("An error occurred while sending the message\n{0}", e.Message));
        }

        return messageResult;
    }

Thank you for suggesting this , but as I mentioned , there is no error captured even in the try/catch bloc I can't just understand why it's not being sent — napi15, Mar 06 '17 at 07:24
Yes , it helped me and the problem was that Twilio.SendMessage() ; do not work for no idea why , but when I used the var message = MessageResource.Create(to:Number ,From:Number :FromNumber, body:Message.toString(); .............the message went threw .....So my conclution was outdated code and outdated library are the reason — napi15, Mar 06 '17 at 19:52
